Load testing Dapr

Before we activate a more complex test infrastructure for Locust on ACI, it is best to first check, and eventually debug, the Locust test locally.

The following steps take us through preparing the data to enabling autoscaling on a running load test:

1. Preparing the data via port-forwarding
2. Testing Locust locally
3. Locust on ACI
4. Configuring the HPA

First, we need to make sure the data in our environment can support our scenario. This is what we’ll do in the next section.
